I fell in love with roses fifteen years ago. My first roses often upset me: either with colorful spots on the leaves, then with white powdery coating of powdery mildew, or some other nuisance. What I just did not do was to heal the rose bushes and prevent diseases ... Over the past five years, fungal diseases in my area have only happened twice and have not had time to do any harm to the rosary. I will share the secrets of preventing fungal infections in the rose garden.Why my roses never get sick with fungal diseases
1 . The place of landing matters
Most often, roses planted in inappropriate places are affected. List of the most inappropriate places:
- deep shadow
- north side of the building
- the most sunshine
- very close to the wall (less than a meter)
- in the lowland
- surrounded by other bushes.
Before buying a rose, go around the site and think - where do you plant it? Choosing a place, replanting a bush every year is a thankless task, you will get tired of waiting for flowers.
2. The bush must be formed without sparing
I remember at the very beginning it was a pity to cut the roses. I carefully, reluctantly, cut off only the branches that suffered after wintering. As a result, after a couple of years it turned out not bushes, but brooms! Dense thickets are a great place for fungal infections, and how many do not spray them with vitriol, the fungus will not recede.
The formation of the bush is not only the correct pruning, thinning, but also help in the location of the branches. After wintering, you need to help the bush straighten out, and when new shoots are actively growing, give them the correct position. So, if the branches are too inclined to the ground - tie in the center of the bush, but if on the contrary, they are directed to the center, pull to the side.
Some varieties with brittle shoots need support, because it is so disappointing when a new strong shoot breaks off from a strong wind.
To fix the shoots, use a stiff wire in a soft winding. Roses do not like rag garters, and plastic clips can damage the stems of young shoots.The rose bush must be cut without sparing.
3. No manure and overdose
Roses love manure. Both cow and horse. Plants respond very well to it, remarkably build up green mass. There is only one “but”: fungi also love manure and remain there for a long time.
Somehow I didn’t like constantly sulking the bushes. Flowers suffer from this. I had to give up manure.
Not worse for roses - chicken droppings. Just do not repeat my mistake! I took chicken litter, rotted, a year ago and, as it was, dry and undiluted, fell asleep under the bushes. The leaves begin to brown - the roots of roses burn. They can be saved only by immediate removal of litter and constant abundant watering.
Attention! You can’t even put old chicken droppings under roses in their pure form! It must be soaked and mixed with humus or peat in proportion: 3 parts of chicken droppings to 7 parts of humus.
Mineral fertilizers for roses are also very necessary. Here are just an overdose of fertilizing - a direct path to disease. This is especially true for overdoses of nitrogen. Roses need 2 complex mineral supplements per season: at the beginning of the first flowering and in August.
4. No mulching and unwanted neighbors
Everyone strives to step on another's rake. I generally danced on them. I listened to all the tips of "smart" gardeners from the Internet. Mulched the ground under roses and black non-woven material, and mowed grass, and even cardboard.
There is nothing good about it! Under the mulch, not only moisture is remarkably preserved, but also pathogens of fungal diseases. In addition, ants feel great there, who take pleasure to graze aphids on young shoots of roses. So - down with the mulch!
Loosening after watering retains moisture in the soil is also very good.
For tips on ground cover plants in the rose garden. Alas and ah. I have not yet been able to find those that would not be susceptible to fungal diseases. If a neighbor gets sick, the disease also goes to roses.Down with the rosary mulch! It helps the spread of mushroom diseases of roses.
5. Watering in the early morning
Other things being equal, morning watering in the summer is preferable. But in spring and autumn, you can water and during the day, the main thing is that the water is not icy.
Not so important when, but watering should be plentiful. If the rose is watered a little, the roots will be located close to the surface and it is likely to freeze in the winter.
Young roses love watering with sweetened water, 5 liters with a tablespoon of sugar is enough for 5 liters. After sweet water, be sure to spill the ground with plain water.
6. Ash is our everything
There is no more universal, cheap and affordable means for roses than ordinary wood ash from the stove or barbecue.
Ash is a fertilizer that is difficult to overdose. Ash allows the shoots to mature faster. But ash is not to the taste of mushroom diseases. If dusting the ground under roses with ash a couple of times a week, then no fungus will survive. Moreover, chicken droppings and other fertilizers acidify the soil, ash helps to quench its acidity.
Before sheltering roses for the winter, as a final chord, I also use ash - you can dust not only the ground, but also the bush itself.
Attention! Ash should not be left in the rain and stored in humid rooms. So she loses her properties.There is no more universal, cheap and affordable means for roses than ordinary wood ash from the stove or barbecue
7. Shower potassium permanganate and other options for its use
Potassium permanganate is another remedy for all cases. I always have it at hand. When roses are pruned or grafted, the instrument is disinfected in a dark saturated solution of potassium permanganate. Cuttings for propagation are also aged in potassium permanganate.
When buying a new flower in a pot, the first thing I do is spill it with potassium permanganate. And if the rose has an open root system, then the roots are also soaked in a raspberry solution for several minutes before planting.
After every rain, especially in autumn, when fog and cold dew begin, I arrange a warm shower for the roses from a pleasant pink solution.
Potassium permanganate, more precisely, its slightly raspberry solution, is also an extra-root dressing for roses at the time of their abundant flowering. But be careful - potassium permanganate crystals that do not dissolve can seriously burn leaves and flowers. Do not be lazy to strain the solution through cheesecloth.

8. All leftovers - to the fire
When pruning roses, raking foliage under them, pruning leaves for the winter, it is important not to store anything on the site. If you put all this in compost, the fungus will multiply perfectly, and the pests will remarkably winter.
9. Go dry for the winter
In the middle lane, roses must be covered. Even if the rose does not freeze without shelter, it will be difficult for it to recover after a difficult wintering. On the other hand, excessive care and shelter of roses ahead of time guarantee fungal diseases, at least.
Year to year is not necessary. There is a dry and long autumn, then there are no problems with leaving for the winter. We wait for frosts, make a "roof", provide ventilation of the shelter. So the roses will remain dry under a dry shelter.
If the forecast is rainy, you will have to tinker a bit. The roof over the rose garden needs to be done early for a week, leaving the plants under the roof to ventilate and dry. Leaves and unripe shoots in this case must be cut off. And for hilling roses you have to take dry purchased (or pre-stored) peat.
Finally, “cover up” the shelter is necessary only at stable subzero temperatures.
Roses for the winter should go dry, so in the rainy autumn they need to arrange shelter before warming.

10. Look at the roses!
Roses wither away without attention. It's true. The more often you look at roses, smell them, take pictures, the less they get sick.
There is no mysticism in this. Just admiring the roses, every day I notice the symptoms of their distress and can quickly help the plants.
Love your roses, and then they will bloom and fragrance!
